Naked-Eye Detection of Fluoride Ions Using a Reaction-based Colorimetric Probe

摘要

Over the past decade,anion recognition has been attracting increased interest in many scientific areas,such as chemistry and biology,and anions have emerged as one of the most important targets in the field of the analytical chemistry.Among them,fluoride ion is considered a micronutrient for human health,preventing dental cavities and promoting healthy bone growth.'This has led to fluoride ions being widely used as additives in toothpaste and drinking water.6 However,high concentrations of fluoride ions in drinking water can induce severe diseases such as fluorosis,gastrointestinal disorders,type II diabetes,and osteosarcoma.Exposure to fluoride ion can also cause attention-deficit/hyperactivity disorder and neurotoxicity,resulting in lower IQ in children.Therefore,fluoride concentration in drinking water must be continuously monitored and preventive measures implemented to control the fluoride level of drinking water.
